What are the fundamental concepts of the OpenERP production module?

The production module in OpenERP (now known as Odoo) is a core module used to manage and control the manufacturing process. It includes production planning, routing, material requirements planning, production orders, inventory management, and production costs.

The basic concepts of production modules include the following aspects:

1. Production schedule: A production schedule refers to the plan made based on market demand and sales forecasts. It involves creating, allocating, and scheduling production orders to ensure products are delivered on time.
2. Crafting route: The crafting route outlines the manufacturing process of a product and the resources required, including production steps, procedures, work hours, material consumption, and quality control.
3. Material Requirements Planning: Material Requirements Planning automatically generates purchase orders for the required raw materials and components based on production plans and process routes. It helps businesses accurately schedule material supply to prevent shortages and excess inventory.
4. Production order: A specific production task generated based on production plans and material requirements planning, containing information such as production quantity, production date, manufacturing process, required materials, and labor hours.
5. Inventory management involves operations such as purchasing, receiving, issuing, and adjusting stock of raw materials and finished goods. It helps businesses to keep track of their inventory in real-time and improve inventory turnover.
6. Production costs refer to the various costs required to manufacture a product, including direct material costs, direct labor costs, and manufacturing expenses. The production module can help companies accurately calculate and control production costs, thus increasing profit margins.

Using the OpenERP production module, businesses can effectively manage production plans, optimize production processes, increase production efficiency and quality, and reduce production costs.
